Write the equation for each line with y {\\displaystyle y} on the left side. If necessary, rearrange the equation so y {\\displaystyle y} is alone on one side of the equal sign. If the equation uses f ( x ) {\\displaystyle f(x)} or g ( x ) {\\displaystyle g(x)} instead of y {\\displaystyle y} , separate this term instead. Remember, you can cancel out terms by performing the same action to both ...Set the right sides of the equation equal to each other. We're looking for a point where the two lines have the same x {\\displaystyle x} and y {\\displaystyle y} values; this is where the lines cross. Both equations have just y {\\displaystyle y} on the left side, so we know the right sides are equal to each other. Write a new equation that represents this. For example, if you want to know ...Solve for x . The new equation only has one variable, x {\\displaystyle x} . Solve this using algebra, by performing the same operation on both sides. Get the x {\\displaystyle x} terms on one side of the equation, then put it in the form x = ? ? {\\displaystyle x=??} .[4] X Expert Source Mario Banuelos, PhD Assistant Professor of Mathematics Expert Interview. 11 December 2021. (If this is ...Use this x {\\displaystyle x} -value to solve for y {\\displaystyle y} . Choose the equation for either line. Replace every x {\\displaystyle x} in the equation with the answer you found.

Example: x = 3 {\\displaystyle x=3} and y = x ...Check your work. It's a good idea to plug your x {\\displaystyle x} -value into the other equation and see if you get the same result. If you get a different solution for y {\\displaystyle y} , go back and check your work for mistakes.[6] X Expert Source Mario Banuelos, PhD Assistant Professor of Mathematics Expert Interview. 11 December 2021. Example: x = 3 {\\displaystyle x=3} and y = 12 − 2 ...Equations for a circle or ellipse have an x 2 {\\displaystyle x^{2}} term and a y 2 {\\displaystyle y^{2}} term. To find the intersection of a circle and a straight line, solve for x in the linear equation.[10] X Research source Substitute the solution for x in the circle equation, and you'll have an easier quadratic equation. These problems can have 0, 1, or 2 solutions, as described in the method above. Thanks Helpful 1 Not Helpful 0A circle and a parabola (or other quadratic) can have 0, 1, 2, 3, or 4 solutions. Find the variable that is squared in both equations — let's say it's x2. Solve for x 2 {\\displaystyle x^{2}} and substitute the answer for the x 2 {\\displaystyle x^{2}} in the other equation. Solve for y to get 0, 1, or 2 solutions. Plug each solution back into the original quadratic equation and solve for x. Each of these can have 0, 1, or 2 solutions.
